Hi!
As I mentioned in my previous post, I was able to make a 50/60 hz multi-region mod on my PAL 1-CHIP SNES console. I followed the steps from a link provided by another user of this forum, and other info that I was able to find online.

Anyway, I though it could be helpful for those wanting to make this mod, to document everything I did in this post. I will first attach all the pictures, and then I will later post a diagram which I think would be self-explanatory on what is need to be done. Any questions please let me know!

The most challenging part was trying to solder the cables onto the lifted pins; I accidentally soldered three contiguous pins on the CPU and had to fix the mess with the solder and a needle. I also recommend that when soldering the cables onto the switch, you start with one of the extremes of the switch and work your way up to the other extreme; do not start with the middle pins.

Note that I did not use hot glue for securing any of the cables. Instead, I used a brown cotton string to segure the cables to the board. I personally think hot glue looks unprofessional, but that is just my personal view.

More pictures coming...

So here is the updated diagram explaining exactly what I did, in case anybody is interested. I got the idea from a user of nfg.forums who posted a similar diagram. However, I updated it with the composite mod (pin 9 of video encoder), a 12 pin switch which can be bought on ebay (instead of 2 switches), and the 5v and ground lines connected directly to the voltage regulator.
